Application filed April 21. 1905. Serial'No. 256,759.`

To all 1117111171 'it may concern:

Be it known that l, ALFRED Ffnnsc'HL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented an Improvement `in lVheels, of which the following is a speciiication.

This invention relates to improvements in class employed in automobiles and involving the use of springs within the tire-casing for yieldingly supporting the tire.

The objects of my invention are to construct a practical atitomobile-ivlieel which while having the necessary resiliency to absorb the usual shocks, and therefore lend the necessary ease in riding, yet cannot become disabled by reason of puiictuies.

A further object in view is to produce an outer metallic rim or tread for the springs, which rim or tread will yield tothe circum ferential expansion and contraction of the springs and which iii connection with a somewhat-similarly constructed wheel-rim will retain the said springs in their proper Working -and relative position.- n

v Various other objects and advantages ofv the invention will hereinafter appear, and the novel features thereof will be particularly l grooves or pockets 11, which correspond to pointed out in the claims.

In the accompanying drawings,A Figure l is1 an elevation of a portion of a wheel embody? ing my invention, a section of the outer cas-- ing being broken away to expose the interior, Fig. 2 is a cross-section thereof. Fig, 3, a portion of the wheel in longitudinal section,

the parts being enlarged; Fig. 4, a detail ofl one of the s ring-sections; Fig. 5, a plan of a portion of t e rim of the wheel.

Like numerals of reference indicate like parts in all the views ofthe drawings.

The riin l ofthe wheel may be formed of any materialas, for instance, Wood or metal, lor a combination of both.

the saine is circumferentially concaved and.

provid/ed along its center and at` intervals with recesses 2, extending transverse the saine. Of course a strip of metal stamped to form these recesses may be secured within the rim, if desired. The edges ofthe rim are in the present instance formed with flanges-3, the same entering into the construction of fastener which l may, do, employ.

4 designates The outer face of is found necessary.

though not 'necessarily the outer casing or shoe, and

the same may be formedoflleather, rubber, or fabric, or a combination of any two.-.o' more materials. In the presentinstance have shown it of leatlier,'ai 1d the treadthere' of may be increased in thickness by the a'dd'i-` tion of one.cr more leatherlayersor rub'berf',r

as indicated at 5, so as to comperisateifor the Wear at this point. i he tread" having become worn by use itl ofcourse can be replaced, as is usual irntire construction.'

Against the inner side'of the tread ofthe tire, i and therefore opposing the 1,1 employ,

a metallic band 6, the same beiiz'geegmntalshape in cross-section and formedonthe arc of a circle about corresponding with that'of the tire. Thisbandis preferably fori-ned of sheet-steel of a proper thickness, and l prefer to'construct vthe-sanie'fso that it Will have some flexibility. This l may` secure in various ways, but prefer toconstruct the bandl for this'purpose in asei'ies of sections "7; Each section7 hasv one or more transverse creases or kinks 8 andonejn neniber.)- or an interlocking slip-'joint l0, so' that whentlie sections are combined or* connected they are capable of such movement as will render the band expansive. 'It will thuisv be seen that the transverse' 4kinks 8 'produce' between themselves' and' the slip-joii'its l() transverse several' spring-sections l`l2'. '(See' 'particuj larly Figs. 2 and 3.) The spring, as before indicated, consists vcfa s ries 'of sections 12,

eacl'iesection comprising a plurality of coils. x

For the purpose of preventing-- the coils or sections from having anytendency tobeconie- Y displaced in a circumferential direction inayprovidelthe rni 1. with holes icppo'- site a coilof. each spring-section and connect said Tcoii with an eyelboltglfi,thel shankof which-passes through the hol'e`13 of the rim roo and'beyond lthe saine is 'provided witha #securing-nut, or l mayprefer sonic other sims ple mode of fastening, if ,the sa'meiii practice .lt Willbe noted although thev spring is formed in sections eaclr .independent of the other yet it ispractically continuous,- iiiasniuch ajs the terminals of eachsecticn are practically in line with those 'cf theneirt adjacent sections.'

The obeot'of thisv arrangement Iisftliat" whenjthe Wheel that, as sliown Eig. f1,

meets `W1tn an obstruction only the section of spring at that point of the Wheel is influenced*tliat is to say, the section thus iniiu# v enced Will yield in a circumferentialdirection only and not radially by a iiatteningout of its coils and imparting a strain to the entire spring, as heretofore in a continuous spring. This dispositionis further enhanced by forniing the metallicband 6 and the case of the rim 1. upon segments of a circle greatorthan the coils, so that the latter merely engage the riml and the band at diametrically opposite points, whereby their frictional contact with these two elements is decreased and the coils more liable. to expandand contract in a circumferential direction. The metallic band being lexible'will also lpartake of such eX- pansion and contraction, such action, however, upon the part vof the band being throu liout the saine, so that very slight play etwcen the sections 7 is necessary to compensate for quite a degree of expansion and contraction on behalf of anyone or more of the spring-sections.

Any ordinary means may be employed for securing the tire-casing upon the rim, and l do not confine myself to that shown. In the present instance, however, the edges :of the tire overlap the iianges 3 4of the rim, as indicated at 16, and over these edges perforated.

rings or bands 17 are mounted. Bolts `18 are passed through the flanges 3 and 16 and the rings or bands 17, and clam ing-nuts 2O serve to retain the'bolts in position. v

Having described'. my invention, what I claim is- 1. The combination with a Wheel provided .with a rim having transverse recesses, of a band encircling the rim and having corresponding recesses and comprising sections having slip-joint interlocking connections,

spring coiled-wire sections of less diameter than the band and rim and interposed bel tween therim and band and having their coils seated in the recesses, means for securing each section against circumferential movement, and an outer casing covering the band and securedt'o the rim.

The combination with a'wheel having a rim provided with transverse recesses, of an Y outer band foi-med of a series of loosely-connected sections and provided with transverse recesses corresponding with those oi the rim, a series oie coiled-Wire sections having their coils engaged by the recesses of the band and rim, and an outer casing or covering secured to the rim.

3. The combination With a wheel lhaving a rim provided With transverse recesses, of a bandconsisting of-a series of sections connected by interlocking slip-joints and having transverse recesses corresponding with those ofthe rim, a series of coiled-wire sections havthe rim and band, and anouter casing or covering connected to the 4; The combination with a wheel having a rim provided with transverse recesses and an outer cyoncaved face, of a band segmental in cross-section and provided with transverse recesses agreeing With those of the rim, a coiled-Wire supportof less diameter than the band and rim and seated in the transverse recesses, whereby it contacts With the band and rim at diametricallyopposite points to the rim.

5. The lcombination With a Wheel having a concaved rim, an outer band segmental in cross-section, interposed sections of coiled Wire and of less diameter than the band and rim, meaiisfor securing said coiled-wire seetions between the band and rim, and an buter casing or covering connected to the rim.

6, The combination Witlila Wheel having a rim, of `an .outer band comprising sections each having a plurality of kinks 8 and terminating in slip-joint members 9 producing transverse recesses 11, coiled-Wire sections 12 engaging the recesses 11, an outer' covering or casing connected to the rim, and means carried by the rim for maintaining the coiled- Wire sections -in position.

7. rEhe combination with a wheel having a. segmental rim, a segmental outer iexible band, intermediate coils of diameters less than the band and rimjan outer casing sere'lative position and yet .permitting of free circumferential' contraction and expansion thereof.
